70 degrees and the roaring flame is 100 degrees so yeah hot hot dont touch
The yellow flame in a Bunsen burner can be as hot as 1000 degrees in centigrade scale.
A Bunsen burner is made out of metal so the tube it has does not melt when the flame gets very hot.
there's the roaring blue flame, which is the hottest out of the three and is about 700 degrees celcius hot. there's also the safety flame, 300 degrees celcius and this flame is only used to show that the bunsen burner is on. it's a yellowish or orangey color. its the least hottest out of the three flames. the blue flame is invisible, so it could be difficult for people to see. its the most commonly used flame and its 500 degrees celcius hot.

A Bunsen Burner
Blue and purple
A bunsen burner with any flame is dangerous, because fire is hot! But, blue flames are hotter than yellow flames.
The most efficient flame that a Bunsen burner can produce should be pale light blue, and almost invisible. A yellow or luminous flame should be avoided as it isn't as hot as the blue flame and leaves sut.
Very hot. 70-100 degrees celcius. HOT!
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
Adjusting the barrel on a bunsen burner increases or decreases the oxygen flow. Making it hotter, or not as hot.
The purpose of the sleeve on a Bunsen Burner is to switch between the blue/transparent flame (the hot one) and the orange one.
